You're right, I'm wrong. I meant root_fs generated thru buildroot is
the reference system, self-sufficient.

I'd say yes. You need to 'mount --bind' the src directories, as usually
the amount of inodes allocated in the root_fs is small (<=100Mb).
I already used for example the root_fs arm, which was cross-compiled
on x86 I presume, and did uclibc/gcc/binutils/xfree compilations on my
ipaq h2210.

I guarantee glibc was never involved in it :). The initrd is uclibc based,
the root_fs also, and my mount is over nfs on sources only. It's cool to
see an ipaq h2210 doing compilation with root_fs. Slow (gcc>=3.x.x) but
cool. :)

hope this helped,
Christian
